-------- = 10
  100

$$\frac{\frac{40 \cdot 157}{50} x}{100} = 10$$

Simplify

Detail solution

Given the linear equation:

((157/50)*40*x)/100 = 10

Expand brackets in the left part

157/50*40*x)/100 = 10

Divide both parts of the equation by 157/125

x = 10 / (157/125)

We get the answer: x = 1250/157
